A reseаrch hypоthesis is thаt the vаriance оf autоmobile stopping distances on wet pavement is substantially greater than those on dry pavement. The research study tested 32 automobiles traveling at the same speeds for stopping distances on wet and dry pavement. On wet pavement, the variance of stopping distances is 32 feet. On dry pavement, the standard deviation is 5 feet. At a .05 level of significance, do the sample data justify the conclusion that the variance in stopping distances on wet pavement is greater than in stopping distances on dry pavement? Choose the correct option about the statements below. 1. This is a one-tailed hypothesis test. 2. This is a two-population variance hypothesis test. 3. The degree of freedom is 30, and the critical value is 2.042 4. The test statistics is 1.28 5. Our sample does not justify the conclusion mentioned above.
